TO'ALL WHOM IT-MAY CONCERN:

Be it known that I, HIFNRYY COULIER, of Philadelphia, county ofPhiladelphia, State of Pennsylvania, have invented an ImprovementginHolders for Lamp-Chimneys; and I do herebydecla're the following to be afull,

clear, and exact description of the same.

My inventionfconsists of a lamp-chimney holder, having springs,constructed andarranged as fully described hereafter, so that they willretain upon the holder either a swelled or cylindrical chimney.

In order to enable others skilled in the art to make and use myinvention, I will now proceed to describe its construction andoperation, refere'ncc being bad to the accompanying drawing, which formsa part of this specification, and in which Figure 1 is a side view of myimproved chimney-holder for lamps,

Figure 2 the same partly intsection,

Figure 3 a plan view, and

Figure 4 a detached view of part of the burner.

Similar letters refer to similar parts throughout the several views. a

A is the usual wick-tnbe,contained inandtsecured to the perforatedcasing B, the latter having at its lower end the usual screw-projection,e, for attachment to the reservoir, and near its upper end a partition,d, of perforated plate or wire gauze."

Dis the circular chimney-holder, and forms a part ofthe dome a, whichvhas the'usual elongated opening,

the casing 13 being so secured to this holder as tobe readily detachedtherefrom. Two ledges, b and f, are formed on this holder, the lower andouter ledge, 12. for receiving the lower end of a cylindrical chimney,E, fig. 2, and the upper and inner lcdge,f, for receiving the lowe rflanged end of the swelled chimney, F, fig. 1.

Three wire rings, 7 h 72, are secured to the holder D, andarescbent'that theirupper ends willbear against I the inside of thecylindrical chimney, when thelatterjrests. on the' ledge b, as seenin-fig. 2, and so that they will overlap the flange of the swelledchimney, when the latter has been adjusted to the led'gefof the holder,as seen in fig. 1, the springs thus servingto holdeither styleof-chiinne'y, whichever it may he desired to use.

There are perforations in the holder between the two ledges, and otherperforations in the ledgef, so that, whichever styleof chimney be used,a'plentiful-supply of air cangain access to it from below;

Ido not desire to claim, in this application, a holder havingledges forreoeivingidiiferent chimneys; but

I claim as my invention, and desire to secure by Letters Pateut- ISprings h h It, so constructed and connected to alamp-chimneyholder asto retain'upon the same either a swelled or a cylindrical chimney, asspecified. I v

Iu-testimonywhereof, have signed my uameto'this specifio'ationin thepresence of two subscribing witnesses.
